ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

Spectra and attenuation profiles of neutrons and gamma rays transmitted through graphite piles were measured by an organic scintillator with an n-γ discrimination technique. The neutrons and gamma rays were produced in a graphite target placed in front of the piles, which were bombarded by 52-MeV protons. The piles were 54 cm high, 90 cm wide, and 11.7, 23.5, and 44.9 cm thick. The energy spectra of neutrons and gamma rays were obtained after unfolding by the FERDO code, from pulse-height distributions. Spectra calculated by use of a Monte Carlo neutron transport code developed for neutrons of energy up to 50 MeV show good agreement with the measured spectra.
